admob 广告代码参考 iOS 奖励视频

Request rewarded video

GADRewardBasedVideoAd has a singleton design, so the following example shows a request to load an ad being made to the shared instance:

SWIFT

OBJECTIVE-C

[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
                                       withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];

To allow videos to be preloaded, we recommend calling loadRequest: as early as possible (for example, in your app delegate's application:didFinishLaunchingWithOptions: method).

Always test with test ads

When building and testing your apps, make sure you use test ads rather than live, production ads. Failure to do so can lead to suspension of your account.

The easiest way to load test ads is to use our dedicated test ad unit ID for iOS rewarded video:

ca-app-pub-3940256099942544/1712485313

It's been specially configured to return test ads for every request, and you're free to use it in your own apps while coding, testing, and debugging. Just make sure you replace it with your own ad unit ID before publishing your app.

For more information about how the Mobile Ads SDK's test ads work, see Test Ads.

Set up event notifications

To set up event notification, insert the line shown in bold before your loadRequest: call:

SWIFT

OBJECTIVE-C

[GADRewardBasedVideoAd sharedInstance].delegate = self;
[[GADRewardBasedVideoAd sharedInstance] loadRequest:[GADRequest request]
                                       withAdUnitID:@"ca-app-pub-3940256099942544/1712485313"];

GADRewardBasedVideoAdDelegate notifies you of rewarded video lifecycle events. You are required to set the delegate prior to loading an ad. The most important event in this delegate isrewardBasedVideoAd:didRewardUserWithReward:, which is called when the user should be rewarded for watching a video. You may optionally implement other methods in this delegate.

Here is an example that logs each event available in GADRewardBasedVideoAdDelegate::

SWIFT

OBJECTIVE-C

- (void)rewardBasedVideoAd:(GADRewardBasedVideoAd *)rewardBasedVideoAd
    didRewardUserWithReward:(GADAdReward *)reward {
  NSString *rewardMessage =
      [NSString stringWithFormat:@"Reward received with currency %@ , amount %lf",
          reward.type,
          [reward.amount doubleValue]];
  NSLog(rewardMessage);
}

- (void)rewardBasedVideoAdDidReceiveAd:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad is received.");
}

- (void)rewardBasedVideoAdDidOpen:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Opened reward based video ad.");
}

- (void)rewardBasedVideoAdDidStartPlaying:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad started playing.");
}

- (void)rewardBasedVideoAdDidClose:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad is closed.");
}

- (void)rewardBasedVideoAdWillLeaveApplication:(GADRewardBasedVideoAd *)rewardBasedVideoAd {
  NSLog(@"Reward based video ad will leave application.");
}

- (void)rewardBasedVideoAd:(GADRewardBasedVideoAd *)rewardBasedVideoAd
    didFailToLoadWithError:(NSError *)error {
  NSLog(@"Reward based video ad failed to load.");
}

Display rewarded video

It is a best practice to ensure a rewarded video ad has completed loading before attempting to display it. The isReady method indicates that a rewarded video ad request has been successfully fulfilled:

SWIFT

OBJECTIVE-C

if ([[GADRewardBasedVideoAd sharedInstance] isReady]) {
  [[GADRewardBasedVideoAd sharedInstance] presentFromRootViewController:self];
}
